Preconditioned alternating projection algorithm for solving the penalized-likelihood SPECT reconstruction problem
PURPOSE: The authors recently developed a preconditioned alternating projection algorithm (PAPA) for solving the penalized-likelihood SPECT reconstruction problem. The proposed algorithm can solve a wide variety of non-differentiable optimization models. This work is dedicated to comparing the perfo...
